Advantages

Push-Button CSS Adjustment

No more messing with shims or tools, the closed side setting is hydraulically-adjusted at the touch of a button to quickly tweak your output size.

Hydraulic Toggle Tensioner

Engage a hydraulic cylinder at the push of a button to quickly set toggle tension, replacing manual spring adjustments and reducing downtime.

Aggressive Nip Angle

Optimized jaw geometry ensures material is gripped firmly throughout the crushing stroke, so there’s no slipping and no need for frequent adjustments.

Pitman “Toe” Protection

If the jaw dies wear past normal limits, a small, replaceable part absorbs the impact, preventing costly damage and eliminating downtime for re-machining.

Jaw-First, Everything Follows

At Diamondback Materials, the entire circuit starts with their Portable Liberty Jaw Crusher. It’s not just first in line, it sets the tone for everything downstream.

A dragline excavator feeds raw material directly into the jaw, where it’s crushed to size before traveling to secondary and tertiary processing.

Operators say it’s simple to maintain, offers push button adjustments, and is built right for their conditions.

Feed size is determined by measuring the longest one-way dimension of the material sample. Projected crusher capacities are based on a material having a work index of 12-14, with a bulk density of 100 lbs/ft3 (1.6 mt/m3). The feed grading must have less than 10% passing the crusher setting. The crusher drive assemblies are to be maintained in good working order with the ability to apply all available horsepower without drive belt slippage. Plant installation to ensure the crusher is able to operate continuously consuming the FLA rating of the motor(s) with the equipment able to accept and discharge material freely. For secondary cone crusher applications to be used in closed circuit applications consult Superior for capacity adjustments.
